 Test `T703` is currently failing on on armhf/linux. The test result shows:

 {{{
 GNU_STACK  0x000000 0x00000000 0x00000000 0x00000 0x00000 RWE 0
 }}}

 Arm compiles via LLVM, but x86_64 executbles compiled via LLVM do not have
 an executable stack.

 The other difference between the x86_64 and Arm is the Arm uses `ld.gold`
 as the linker. Sure enough, adding `-optl -Wl,-z,noexecstack` to the ghc
 command line fixes this, but a better solution is needed.

 This is probably also an issue on AArch64 which also uses the `ld.gold`
 linker.
